We kindly ask that no one interprets this as implying that putting herbs on your supper is an acceptable replacement for being immunized. Despite this, a chemical found in rosemary (Salvia Rosmarinus) is being considered for further development as a COVID-19 therapy.
Many compounds have shown antiviral activity in the test tube, which has prompted more study, most of which has been unsuccessful.
Researchers continue to be intrigued by carnosic acid since it has two completely distinct mechanisms of activity that might be beneficial in treating the same illness.
Before the pandemic, carnosic acid, which makes up approximately 2% of rosemary’s dry weight, was studied for its anti-inflammatory effects on the brain.
Traditional medicines have been using the herb itself and its oil, at least since the time of the Romans.
In a more recent study, it has been shown that carnosic acid inhibits the NLRP3 inflammatory pathway, which has been linked to long-term COVID and Alzheimer’s, and Parkinson’s disease.
Researchers at the Scripps Institute for Public Health analyze these findings in a recent work published in Antioxidants. They propose another mechanism through which carnosic acid might have anti-COVID-19 capabilities.
According to the study’s principal author Professor Stuart Lipton, “we believe that carnosic acid, or some optimized derivative, is worth pursuing as a potentially inexpensive, safe, and effective therapy for COVID-19 and some other inflammation-related illnesses.”
Dr. Chank-ki Oh discovered that carnosic acid inhibits SARS-ability CoV-2’s to contaminate cells. It is considered to accomplish this by interfering with the virus’s famed spike protein’s ability to latch onto ACE2 receptors on human cells, which is thought to be the case.
In cell culture experiments, Dr. Oh discovered that carnosic acid is over ninety percent efficient in inhibiting SARS-CoV-2 infection.
It is unrelated to how carnosic acid and its derivative carnosol, which may also be seen in rosemary, block NLRP3 inflammatory responses.
According to the article, NLRP3 has been related to the cytokine storms that may be dangerous during acute COVID and the “brain fog” and anxiety during long-term COVID.
When Lipton wrote about the potential benefits of carnosic acid, he said it showed indications of being a “Pathologically activated therapeutic inactive and harmless un its usual condition, but transformed to an active form when it was needed to be active.”
In test tubes, a nearly unlimited variety of substances either kill or inhibit COVID-19. Still, the vast majority of these compounds fail when introduced to live organisms for one reason or another.
The results in vitro sparked interest in hydroxychloroquine and Ivermectin, which are now being promoted as COVID therapies. However, we are not aware of any proof that urine may kill virus cells, even in test tubes.
With the possibility of a similar outcome, the only incentive to include rosemary in your meals is if you like the taste; yet, the Scripps team is hopeful that they have discovered something valuable that will someday establish its usefulness.
Carnosic acid may also be found in sage, a close cousin of rosemary. It is hoped that the advantages of thyme will be shown.
